Locational Privacy

Locational Privacy

Modern communications mean most individuals today walk around with a beacon that transmits their location. Mobile phones register to a nearby tower as the owner moves through space and the phone company can collect that data in real time or retrospectively to physically place the phone with varying degrees of accuracy. Companies can also determine the owner of every handset within range of a particular tower. GPS enabled phones enable far more precise location placement. Many cars now have GPS devices installed some of which transmit the vehicle’s location to a centralized service. As the devices get cheaper and smaller law enforcement agencies can more easily attach GPS trackers to cars and individuals enabling precise round-the-clock surveillance without ever leaving the precinct. Location-based services including maps of nearby restaurants friend finders and other social networks collect location data as part of providing the service or for contextual advertising.

EFF is fighting to protect the privacy and prevent the misuse of this data that users of phones GPS transmitters and location-based services leak to providers and to the government. In our cell tracking and GPS tracking cases we advocate that the law protect this information by requiring police to get a search warrant before obtaining this sensitive data. We also work to ensure that location based service providers don’t abuse the information they collect on their customers or hand it off to other companies or the police without consent or probable cause.

The EFF has weighed in on this trend with a timely whitepaper: On Location Privacy and How to Avoid Losing It Forever. The paper includes a number of scenarios with actionable solutions and a number of reason why companies should care.

In a whitepaper, "On Locational Privacy, and How to Avoid Losing it Forever," Peter Eckersley, staff technologist for the Electronic Frontier Foundation, and Andrew Blumberg, a postdoctoral fellow at Stanford University, argue that modern cryptography allows data processing systems to be designed with privacy policies ranging from limited to complete...

The Electronic Frontier Foundation said the regulations would let insurance companies require customers' cars to be outfitted with electronic devices “that could transmit back to the insurance companies all sorts of data about car motion (acceleration, braking, and so forth) as well as driver behavior (steering and seat-belt wearing).”

This week, the United Kingdom's Interception of Communications commissioner, Sir Paul Kennedy, announced his latest statistics for Britain's phone and email surveillance systems, to generally shocked responses by the British Public. In 2008, law enforcement, local authorities and the secret services in that country demanded "communication data" —...
